Lorries bound for Dover could be redirected if no trade deal is reached before Brexit

Speculation is growing about the possibility of a no-deal Brexit in Sunday's papers.

The Sunday Telegraph reports that ministers have drawn up plans to redirect British food exports to Belgium and the Netherlands, should no agreement be reached.

Under the proposals, lorries bound for Dover would be redirected to ports in the east of England, such as Felixstowe, rather than waiting in emergency lorry parks on the motorway network in Kent.

In its editorial, the Sunday Times calls for "a little sober reflection" on Brexit, warning the "brinkmanship of some of the no-deal warnings risks turning them into self-fulfilling prophecies".

The paper says the EU's current negotiating position "will require some softening" for there to be any chance of a settlement, "just as there may be further compromises from Britain".

RAF jet spy

An apparent spy plot to uncover confidential information about the UK's new £9bn fleet of fighter jets is the Mail on Sunday's splash.

An internal RAF memo reveals a female secret agent hacked into the online dating profile of a serving airwoman, striking up conversations with unsuspecting male colleagues - one of whom was persuaded to reveal details of the F-35 Lightning jets.

The memo goes on to say "little information was disclosed", but the paper's defence editor, Mark Nicol, describes it as a "deeply damaging and highly embarrassing" security breach.

"Portugal's skies turn orange" is how the Observer describes the impact of continuing forest fires in the south of the country, where temperatures climbed well above 40C on Saturday.

The paper says typically busy tourist towns have been left deserted at the height of the summer season, while even locals used to the heat "are retreating indoors".

In neighbouring Spain, the Sunday People reports on the deaths of three people from heatstroke, including a middle-aged homeless man who collapsed on a street in Barcelona.

Inmate driving lessons

The Sunday Express debates whether prisoners should be allowed to learn to drive as part of their rehabilitation.

Figures obtained through a Freedom of Information request show that in 2016, almost 150 inmates - some of them serving life sentences - were granted temporary release to take lessons.

The Centre for Crime Prevention said it was "staggering", and questioned the government's commitment to public safety.

But the Ministry of Justice said the ability to drive could improve a prisoner's "future employment prospects", and insisted all inmates were thoroughly risk-assessed.

Salisbury revival

And as Salisbury recovers from the recent Novichok poisonings, the Sunday Mirror reports on the efforts of a local band to revive visitor numbers through music.

Pete Aves and The Manuals hope their track, "The Ballad of Salisbury Town", will cast the city in a "more positive light" - with jolly lyrics such as "we could go to the square, the market is there, if you buy a peach, then I'll pick a pear".

Proceeds from the song, which has been released as a download, will be donated to charity.
